Testing the application

Now that we have the code implemented, we can run a few test cases to see if the code works as expected. If you look at the code, we have an oven_temp variable that in real life would be tied to some type of thermal sensor. For our purposes, we are going to control it manually to simulate the conditions inside the oven. In real-world automation programming, this is a common technique. We don’t always want to heat the oven to the target temperature until we know for sure the software is working; simply writing values to that variable will suffice. With all that being said, we can now start testing the application by testing out the door.

Testing the door lock

We are going to start with the most basic and safety-critical part: testing the door. Essentially, we want to ensure the door is locking and unlocking properly. For this, we are going to use the following test case:
